ruby-on-rails - 安装Ruby Gems

当我运行诸如

gem install heroku

或

gem update --system

我收到警告

ERROR:  Could not find a valid gem 'heroku' (>= 0) in any repository
ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
Errno::ECONNREFUSED: No connection could be made because the target machine
actively refused it. - connect(2) (http://rubygems.org/latest_specs.4.8.gz)

我已经浏览了几篇相关的帖子，其中大部分都暗示了网络问题；我关闭了所有的防病毒/防火墙软件，但运气不佳。请注意，同一网络上的其他人没有面临这些问题。我对如何进行感到困惑。

最佳答案

旧帖子，但这可能会帮助其他人。指定代理。即使已经设置了http_proxy环境变量，这似乎仍然有效：

gem install heroku --http-proxy http://yourproxyserver:port
